I-Bus is a data bus that is in the car.
The Resler I-Bus adapter is an I-Bus-to-USB converter that allows android devices (equipped with a USB port) to read data from the I-Bus.
Couple a Resler I-Bus-to-USB adapter with an Android device running the I-Bus android app and you have a very decent monitoring system.
